There is an issue introduced with a recent OpenSSL 1.0.2k update where a pkgin upgrade will render the pkg_install tools (which includes pkgin) unusable, due to removing the previous openssl package prior to installing the update.

Here is an example error message you would see when attempting to use pkgin:

New naming scheme and introduction of Long Term Support (LTS) releases:

All image names now include the architecture information. For example minimal-32 for 32-bit, minimal-64 for 64-bit and minimal-multiarch for multiarch.

All fourth quarter (Q4) pkgsrc releases are now LTS releases. Packages in an LTS release will receive security or build fixes for 3 years from the time the release is made available (assuming the fixes do not affect API or ABI compatibility)

Images based on a pkgsrc LTS release will have a new -lts suffix added to the image name e.g., minimal-32-lts
